Center node: "querying source code with natural language"
  Abstract: One common task of developing or maintaining software is searching the source code for information like specific method calls or write accesses to certain fields. This kind of information is required to correctly implement new features and to solve bugs. This paper presents an approach for querying source code with natural language.

Connected through hyperedge HE-1 (induced by source paper "effective reformulation of query for code search using crowdsourced knowledge and extra large data analytics"):
  with members:
    - "strict information retrieval based search term identification for concept location"
    - "improved query reformulation for concept location using coderank and document structures"
    - "nlp2code code snippet content assist via natural language tasks"
    - "enriching word vectors with subword information"
    - "rack automatic api recommendation using crowdsourced knowledge"
    - "quickar automatic query reformulation for concept location using crowdsourced knowledge"
    - "query expansion based on crowd knowledge for code search"
    - "towards a context aware ide based meta search engine for recommendation about programming errors and exceptions"

Connected through hyperedge HE-2 (induced by source paper "verifiable source code documentation in controlled natural language"):
  with members:
    - "a survey and classification of controlled natural languages"
    - "a multilingual semantic wiki based on attempto controlled english and grammatical framework"
    - "how controlled english can improve semantic wikis"
