get-synonyms clj deprecated

DEPRECATED. Use synonyms instead.

historical-associations clj

(historical-associations svc component-id)

Returns all historical-type associations for the specified component. Result is a map, keyed by the type of association (e.g. SAME-AS) and a sequence of reference set items for that association. Some concepts may be ambiguous and therefore map to multiple targets. Annoyingly, but understandably, the 'moved-to' reference set does not actually reference the new component - but the namespace to which it has moved - so for example an ancient International release may have accidentally including UK specific concepts - so they will have been removed. It is hoped that most MOVED-TO concepts will also have a SAME-AS or POSSIBLY-EQUIVALENT-TO historical association.

See https://confluence.ihtsdotools.org/display/DOCRELFMT/5.2.5.1+Historical+Association+Reference+Sets and https://confluence.ihtsdotools.org/display/editorialag/Component+Moved+Elsewhere

Note: Unlike some other functions that deal with historical associations, this returns the reference set items themselves and will include both active and inactive reference set items. Other functions usually only take into account active reference set items.

history-profile clj

(history-profile svc profile)

Returns a set of reference sets matching the named profile. Use in conjunction with with-historical:

(with-historical svc [24700007] (history-profile :HISTORY-MIN)

See https://confluence.ihtsdotools.org/display/DOCECL/6.11+History+Supplements

import-snomed clj

(import-snomed root dirs)

Import SNOMED distribution files from the directories dirs specified into the database directory root specified.

Import is performed in three phases for each directory:

1. import of core components and essential metadata, and
2. interim indexing
3. import of non-core and extension files.

Interim indexing is necessary in order to ensure correct reification in subsequent import(s).

index clj

(index root)

(index root language-priority-list)

Build search indices for the database in directory 'root' specified.

installed-reference-sets clj

(installed-reference-sets svc)

Return a set of identifiers representing installed reference sets.

intersect-ecl clj

(intersect-ecl svc concept-ids ecl)

Returns the subset of the concept identifiers that satisfy the SNOMED ECL expression.

log-metadata clj

(log-metadata dir)

map-concept-into clj

(map-concept-into svc concept-id target)

Returns a set of concept identifiers representing the result of mapping a single concept into the target. For efficiency, it is almost always better to use map-into with a collection of identifiers, as the target will be then determined only once for all identifiers to be processed.

map-features clj deprecated

(map-features svc source-concept-ids target)

DEPRECATED: Use map-into instead.

map-into clj

(map-into svc source-concept-ids target)

Map the source-concept-ids into the target, usually in order to reduce the dimensionality of the dataset. Returns a sequence of sets of identifiers that are in the 'target'. The target can be a collection of identifiers, an ECL expression or, for convenience, an identifier representing a reference set. The latter two will be expanded into a set of identifiers.

Parameters:

• svc : hermes service
• source-concept-ids : a collection of concept identifiers
• target : one of: - a collection of concept identifiers - an ECL expression - a refset identifier

If a source concept id resolves to multiple concepts in the target collection, then a collection will be returned such that no member of the subset is subsumed by another member.

Callers will usually need to map any source concept identifiers into their modern active replacements, if they are now inactive, as inactive source concepts do not have relationships that can be used to perform map-into.

The use of 'map-into' is in reducing the granularity of user-entered data to aid analytics. For example, rather than limiting data entry to the UK emergency reference set, a set of commonly seen diagnoses in emergency departments in the UK, we can allow clinicians to enter highly specific, granular terms, and map to the contents of that reference set as required for analytics and reporting.

For example, '991411000000109' is the UK emergency unit diagnosis refset:

(map-into svc [24700007 763794005] 991411000000109)
     =>  (#{24700007} #{45170000})

As multiple sclerosis (24700007) is in the reference set, it is returned. However, LGI1-associated limbic encephalitis (763794005) is not in the reference set, the best terms are returned ("Encephalitis" - 45170000).

This can be used to do simple classification tasks - such as determining the broad types of illness. For example, here we use ECL to define a set to include 'neurological disease', 'respiratory disease' and 'infectious disease':

(map-into svc [24700007 763794005 95883001] "118940003 OR 50043002 OR 40733004")
    => (#{118940003} #{118940003} #{40733004 118940003})

Both multiple sclerosis and LGI-1 encephalitis are types of neurological disease (118940003). However, 'Bacterial meningitis' (95883001) is mapped to both 'neurological disease' (118940003) AND 'infectious disease' (40733004).

match-locale clj

(match-locale svc language-range)

Return an ordered sequence of refset ids that are the best match for the required language range. language-range should be a single string containing a list of comma-separated language ranges or a list of language ranges in the form of the "Accept-Language " header defined in RFC3066.

member-field clj

(member-field svc refset-id field s)

Returns a set of referenced component identifiers that are members of the given reference set with a matching 'value' for the 'field' specified. For example, to perform a reverse map from ICD-10:

(member-field svc 447562003 "mapTarget" "G35")

member-field-prefix clj

(member-field-prefix svc refset-id field prefix)

Return a set of referenced component identifiers that are members of the given reference set with a matching prefix 'value' for the 'field' specified. Example:

    (member-field-prefix svc 447562003 "mapTarget" "G3")

member-field-wildcard clj

(member-field-wildcard svc refset-id field s)

Return a set of referenced component identifiers that are members of the given reference set with a matching wildcard 'value' for the 'field' specified. Supported wildcards are *, which matches any character sequence (including the empty one), and ?, which matches any single character. '' is the escape character. Example:

    (member-field-wildcard svc 447562003 "mapTarget" "G3?")

module-dependencies clj

(module-dependencies svc)

Returns a sequence of module dependencies, containing:

• :source : source of the dependency (a map of :moduleId, :version)
• :target : target on which the source depends (a map of :moduleId, :version)
• :actual : actual version; may be nil
• :valid : is this dependency satisfied and consistent? Versions are represented as `java.time.LocalDate. Dependencies are not transitive as per [[https://confluence.ihtsdotools.org/display/DOCRELFMT/5.2.4.2+Module+Dependency+Reference+Set]].

module-dependencies* clj

(module-dependencies* items)

Given a collection of module dependency reference set items, return transformed as :source, :target, :actual and :valid representing module dependencies. Returns a sequence of:

• :source : source of the dependency (a map of :moduleId, :version)
• :target : target on which the source depends (a map of :moduleId, :version)
• :actual : actual version; may be nil
• :valid : is this dependency satisfied and consistent? Versions are represented as `java.time.LocalDate. Dependencies are not transitive as per [[https://confluence.ihtsdotools.org/display/DOCRELFMT/5.2.4.2+Module+Dependency+Reference+Set]].

module-dependency-problems clj

(module-dependency-problems svc)

Returns a human-readable report of invalid dependencies and version mismatches.

mrcm-domains clj

(mrcm-domains {:keys [store memberSearcher] :as svc})

Return a sequence of MRCM Domain reference set items for the given service. Each item essentially represents an 'MRCM domain'.

open clj

(open root)

(open root {:keys [quiet] :or {quiet false}})

Open a (read-only) SNOMED service from root, which should be anything coercible to a java.io.File

parent-relationships clj

(parent-relationships svc concept-id)

Returns a map of the parent relationships keyed by type.

parent-relationships-expanded clj

(parent-relationships-expanded svc concept-id)

(parent-relationships-expanded svc concept-id type-id)

Returns a map of the parent relationships, with each value a set of identifiers representing the targets and their transitive closure tables. This makes it trivial to build queries that find all concepts with, for example, a common finding site at any level of granularity.

parent-relationships-of-type clj

(parent-relationships-of-type svc concept-id type-concept-id)

Returns a set of identifiers representing the parent relationships of the specified type of the specified concept.

parse-expression clj

(parse-expression _svc s)

paths-to-root clj

(paths-to-root svc concept-id)

Return a sequence of paths from the concept to root node. Each path is a sequence of identifiers, starting with the concept itself and ending with the root node.

e.g.

(paths-to-root svc 24700007)
=>
((24700007 6118003 80690008 23853001 118940003 362965005 64572001 404684003 138875005)
 (24700007 6118003 80690008 23853001 246556002 404684003 138875005)
 (24700007 6118003 80690008 362975008 64572001 404684003 138875005)
 (24700007 39367000 23853001 118940003 362965005 64572001 404684003 138875005)
 (24700007 39367000 23853001 246556002 404684003 138875005)
 (24700007 39367000 363171009 362965005 64572001 404684003 138875005)
 (24700007 39367000 363171009 363170005 128139000 64572001 404684003 138875005)
 (24700007 414029004 64572001 404684003 138875005))

pprint-properties clj

(pprint-properties svc props {:keys [key-fmt value-fmt fmt language-range]})

Pretty print properties. Keys and values can be formatted using fmt or separately using key-fmt and value-fmt. Valid formats are: :map-id-syn : map of id to synonym :vec-id-syn : vector of id and synonym :str-id-syn : id and synonym as a string :syn : synonym :id : id language-range should be a language range such as "en-GB".

preferred-synonym clj

(preferred-synonym svc concept-id)

(preferred-synonym svc concept-id language-range)

Return the preferred synonym for the concept based on the language preferences specified.

Use match-locale and then repeated calls to preferred-synonym* if preferred synonyms of a number of concepts are required (e.g. in a map/reduce etc)

Parameters:

• svc : hermes service
• concept-id : concept identifier
• language-range : a single string containing a list of comma-separated language ranges or a list of language ranges in the form of the "Accept-Language " header defined in RFC3066.

preferred-synonym* clj

(preferred-synonym* svc concept-id language-refset-ids)

Given an ordered sequence of preferred language reference set ids, return the preferred synonym for the concept specified.

properties clj

(properties svc concept-id)

(properties svc concept-id {:keys [expand]})

Returns a concept's properties, including concrete values. Ungrouped properties are returned under key '0', with other groups returned with non-zero keys. There is no other intrinsic meaning to the group identifier.

Attribute values will be returned as a set of values optionally expanded to include the transitive relationships. If the value for the attribute is a concrete value or the SNOMED machine-readable concept model (MRCM) for the attribute in the context of the concept's domain states that the cardinality of the property is 0..1 or 1..1 and the values are not expanded to include transitive dependencies, the value will be unwrapped to a single value.

e.g. for lamotrigine:

(properties svc (properties svc 1231295007))
=>
{0 {116680003 #{779653004}, 411116001 385060002, 763032000 732936001,
    766939001 #{773862006}, 1142139005 "#1"},
 1 {732943007 387562000, 732945000 258684004, 732947008 732936001,
    762949000 387562000, 1142135004 "#250", 1142136003 "#1"}}

See https://confluence.ihtsdotools.org/display/DOCRELFMT/4.2.3+Relationship+File+Specification "The relationshipGroup field is used to group relationships with the same sourceId field into one or more logical sets. A relationship with a relationshipGroup field value of '0' is considered not to be grouped. All relationships with the same sourceId and non-zero relationshipGroup are considered to be logically grouped."

refset-descriptor-attribute-ids clj

(refset-descriptor-attribute-ids svc refset-id)

Return a vector of attribute description concept ids for the given reference set.

refset-item clj

(refset-item svc uuid)

Return a specific refset item by UUID.

refset-members clj

(refset-members svc refset-id & more)

Return a set of identifiers for the members of the given refset(s).

Parameters:

• refset-id - SNOMED identifier representing the reference set.

relationship clj

(relationship svc relationship-id)

Return the relationship with the specified identifier.

release-information clj

(release-information svc)

Returns descriptions representing the installed distributions. Ordering will be by date except that the description for the 'core' module will always be first. See https://confluence.ihtsdotools.org/display/DOCTIG/4.1.+Root+and+top-level+Concepts

reverse-map clj

(reverse-map svc refset-id code)

Returns a sequence of reference set items representing the reverse mapping from the reference set and mapTarget specified. It's almost always better to use member-field or member-field-prefix directly.

A code in a target codesystem may map to multiple concepts. Each concept may map to multiple codes in that target codesystem. reverse-map-prefix returns only results that would meet the original criteria. This mimics the original behaviour of an older implementation and should be regarded as semi-deprecated. For more control, use member-field.

reverse-map-prefix clj

(reverse-map-prefix svc refset-id prefix)

Returns a sequence of reference set items representing the reverse mapping from the reference set and mapTarget. It is almost always better to use member-field or member-field-prefix directly.

A code in a target codesystem may map to multiple concepts. Each concept may map to multiple codes in that target codesystem. reverse-map-prefix returns only results that would meet the original criteria. This mimics the original behaviour of an older implementation and should be regarded as semi-deprecated. For more control, use member-field-prefix.

search clj

(search svc params)

Perform a search against the index.

Parameters:

• svc : hermes service
• params : a map of search parameters, which include:

keyword	description (default)
:s	search string to use
:max-hits	maximum hits (if omitted returns unlimited but
	unsorted results)
:constraint	SNOMED ECL constraint
:fuzzy	fuzziness (0-2, default 0)
:fallback-fuzzy	if no results, try fuzzy search (0-2, default 0).
:remove-duplicates?	remove duplicate results (default, false)

Example: to search for neurologist as an occupation ('IS-A' '14679004')

(do-search searcher {:s "neurologist" :constraint "<14679004"})

For autocompletion, it is recommended to use fuzzy=0, and fallback-fuzzy=2.

There are some lower-level search parameters available, but it is usually more appropriate to use a SNOMED ECL constraint instead of these.

keyword	description (default)
:query	additional Lucene ^Query to apply
:show-fsn?	show FSNs in results? (default, false)
:inactive-concepts?	search descriptions of inactive concepts? (false)
:inactive-descriptions?	search inactive descriptions? (default, true)
:properties	a map of properties and their possible values.
:concept-refsets	a collection of refset ids to limit search

The properties map contains keys for a property and then either a single identifier or vector of identifiers to limit search. For example

(do-search searcher {:s "neurologist" :properties {snomed/IsA [14679004]}})

However, concrete values are not supported, so to search using concrete values use a SNOMED ECL constraint instead.

A FSN is a fully-specified name and should generally be left out of search.

some-indexed clj

(some-indexed pred coll)

Returns index and first logical true value of (pred x) in coll, or nil.

e.g.

(some-indexed #{64572001} '(385093006 233604007 205237003 363169009 363170005 123946008 64572001 404684003 138875005))

returns: [6 664572001]

source-historical clj

(source-historical svc component-id)

(source-historical svc component-id refset-ids)

Return the requested historical associations for the component of types as defined by refset-ids, or all association refsets if omitted.

source-historical-associations clj

(source-historical-associations svc component-id)

Returns all historical-type associations in which the specified component is the target. For example, searching for 24700007 will result in a map keyed by refset-id (e.g. SAME-AS reference set) and a set of concept identifiers.

status clj

(status root)

(status root {:keys [log?] :as opts})

Return status information for the database at 'root'.

status* clj

(status* svc
         {:keys [counts? modules? installed-refsets?]
          :or {counts? true installed-refsets? false modules? false}})

stream-all-concepts clj

(stream-all-concepts svc ch)

(stream-all-concepts svc ch close?)

Streams all concepts on the channel specified. By default, closing the channel when done. Blocking, so run in a background thread.

subsumed-by? clj

(subsumed-by? svc concept-id subsumer-concept-id)

Is concept-id subsumed by subsumer-concept-id?

synonyms clj

(synonyms svc concept-id)

Returns a sequence of synonyms for the given concept.

transitive-synonyms clj

(transitive-synonyms svc params)

Returns all synonyms of the specified concepts, including those of its descendants.

Parameters:

• svc : hermes service

• params : search parameters to select concepts; one of:

    - a map        : search parameters as per [[search]]
    - a string     : a string containing an ECL expression
    - a collection : a collection of concept identifiers
  

valid-ecl? clj

(valid-ecl? s)

Is the ECL valid? This does not attempt to expand the ECL, but simply checks that it is valid ECL according to the grammar.

with-historical clj

(with-historical svc concept-ids)

(with-historical svc concept-ids refset-ids)

For a given sequence of concept identifiers, expand to include historical associations both backwards and forwards in time.

For a currently active concept, this will return historic inactivated concepts in which it is the target. For a now inactive concept, this will return the active associations and their historic associations.

By default, all types of historical associations except MoveTo and MovedFrom are included, but this is configurable.
