ad hoc information retrieval
Feature Based Selection of Dependency Paths in Ad Hoc Information Retrieval
... Techniques that compare short text seg- ments using dependency paths (or simply, paths) appear in a wide range of automated language processing applications including question answering (QA). However, few models in ...

Topic based language models for ad hoc information retrieval
... Abstract— We propose a topic based approach to language modelling for ad-hoc Information Retrieval (IR). Many smoothed estimators used for the multinomial query model in IR rely upon the ...
