semanticanalyser-py 0.1.0

A Python binding for the Semantic Analyser service maintained by BODC

semanticanalyser-py

A lightweight Python client for the BODC Semantic Analyser API. It helps you discover controlled vocabularies, explore categories, match types and properties, and run term analysis to resolve terms to canonical concepts (with codes and URIs) across marine community vocabularies, including BODC NVS.

The project is authored by Ahmad Mahmoud during his internship at CNR-IIA.

Key features

• Retrieve semantic categories
• List supported vocabularies
• Discover supported match types and match properties
• Analyse free-text terms and obtain matched concepts, codes, and vocabularies
• Simple, Pythonic API with minimal dependencies

Installation

pip install semanticanalyser-py

Quick start

# Basic usage example
from analyser import SemanticAnalyzer, Matchtype, MatchProperty

analyser = SemanticAnalyzer()  # uses the public BODC endpoint by default

# Explore categories
categories = analyser.get_categories()
print("Categories:", categories)

# Choose a category (e.g., first one) and list vocabularies
if categories:
    cat_code = categories[0]["termCode"]
    vocabs = analyser.get_vocabularies(cat_code)
    for v in vocabs:
        print(v)

# Discover matching options
match_types = analyser.getMatchTypes()         # e.g., ["exact", "broad", ...]
match_props = analyser.getMatchProperties()    # e.g., ["prefLabel", "altLabel", ...]

# Prepare the query
terms = ["dissolved oxygen", "chlorophyll a"]

# Optionally filter or construct match types/properties
# (example below demonstrates using them as returned)
analysis = analyser.analyzeTerms(
    terms=terms,
    matchTypes=match_types,
    matchProperties=match_props
)

if analysis:
    for m in analysis.get_matches():
        print(
            m.getMatchingTerm(),
            m.getMatchProperty(),
            m.getMatchType(),
            m.getTermCode(),
            m.getVocabulary(),
            m.getConceptURI(),
        )

When to use this library

• You need to map free-text terms to standardised concepts and codes
• You’re enriching marine dataset descriptions with semantic metadata (URIs, codes, vocabularies)

Configuration

• Endpoint: By default, the client targets the public BODC Semantic Analyser API. You can override the endpoint:

  from analyser import SemanticAnalyzer
  analyser = SemanticAnalyzer(endpoint="https://semantics.bodc.ac.uk/api")

Requirements

• Python: 3.8 or newer
• Dependencies: requests

Roadmap ideas

• Robust pagination and retry logic
• Additional helpers for filtering results
• CLI utilities
