Package: taxonomy-matcher
taxonomy-matcherCI StatusDescriptionGiven a gazetteer/taxonomy and input text,taxonomy-matchercan
be used to find all phrases which matches the codes/instances/keywords in the
gazetteer or taxonomy.For each match, it will return the information of,surface_formmatched positionCode ID and Code Descriptionand other code related informationRequirementsPython 3.6+UsageUse taxonomy-match script:usage: taxonomy-match input_file taxonomy_file [--output_file OUTPUT_FILE]


load taxonomy phrases from the taxonomy file, and find all matched phrases
from the input text. The result will eithor write to an output file or print
to the screen.

positional arguments:
  input_file            input text file, text to mine phrases
  taxonomy_file         taxonomy file, support json/xml/txt, see documentation
                        for more details

optional arguments:
  --output_file         output file of matched phrases, supports
                        jsonl/csv/tsv/txt format, print matched phrases to
                        the screen if not definedUse taxonomy-matcher moduleFrom normalization table in JSOM format:from taxonomy_matcher.matcher import Matcher

ct_matcher = Matcher(codetable=ct_file)
for matched in ct_matcher.matching(text):
    print(matched)CodeTable is a XML version of the JSON example given above.other functionsContext words:When context are needed for matched phrases, e.g. for the following up
validation functions, enable thewith\_contextoption:from taxonomy_matcher.matcher import Matcher
taxonomy_matcher = Matcher(normtable=json_file,with_context=True)
for matched in taxonomy_matcher.matching(text):
    print(matched.left_context, matched.right_context)Code Property lookupIf need to lookup the property of an Code in the taxonomy,
check the matcher Class property ‘code_property_mapping’,
it is a dictionary mapping id to description and category, it is in
the form of:dict[code_id] = {
    'desc':code_description,
    'type':code_category
}E.g. to get the description of the codeid:codeid = 12345
from taxonomy_matcher.matcher import Matcher
taxonomy_matcher = Matcher(normtable=json_file)
if codeid in taxonomy_matcher.code_property_mapping:
    print(taxonomy_matcher.code_property_mapping[codeid]['desc'])check the Metainfo of the Taxonomy or Gazetteer:Note: currently only available for the Normalized code JSOM.The metainfo can be stored in meta part of the JSON document, e.g. if
the following information is listed in the JSOM meta section:"meta": {
  "language": "EN",
  "release_datetime": "2019-04-17T12:22:10.729673",
  "concept_type": "skills",
  "purpose": "normalization"
},We can fetch it via the matcher objectfrom taxonomy_matcher.matcher import Matcher
taxonomy_matcher = Matcher(normtable=json_file)
print(taxonomy_matcher['meta_info'])output will be:{

the instance has the following attributes:normalize pattern form: matched_patternsurface form: surface_formstart position and end position: start_pos, end_poscode_id and code_description (None if not set in the pattern file)left context and right context of the matched skills (only availabe if with_context=True )for match in matcher.matching(text):
