Summary
This is a survey paper about biomedical text mining in 2005.
They describe the state of the art in 2005 for each distinct type of text-mining task below.
- Named entity recognition
- Problems
- No complete dictionary for most types of biological named entities
- ambiguous words and phrases
- multi names
- approaches are mainly categorized into three below
- lexicon based
- rule based
- statistically based
- performance
- overall, the performance of gene and protein NER systems is F-scores between 75 and 85 percent.
- Problems
- Text classification
- Synonym and abbreviation extraction
- Synonym
- use dictionary
- automatic extraction of gene name synonyms from biomedical free text
- SVM classifier-based
- pattern-based
- abbreviation
- either the full form or the abbreviation is often enclosed in parentheses.
- a variety of alignment and scoring methods
- Synonym
- Relationship extraction
- detect occurrences of a prespecified type of relationship between a pair of entities of given types
- manually generated template-based methods
- automatic template methods
- statistical methods
- NLP-based methods
mostly are about the relationships between genes and proteins
- Hypothesis generation
- uncover relationships that are not present in the text but instead are inferred by the presence of other more explicit relationships. uncover previously unrecognized relationships
- Integration frameworks
- integrated text-mining frameworks

The widely cited Pang et al EMNLP 2002 paper was influenced by this paper - but considers supervised learning techniques. The choice of movie reviews as the domain was suggested by the (relatively) poor performance of Turney's method on movies.
An interesting follow-up paper is Turney and Littman, TOIS 2003 which focuses on evaluation of the technique of using PMI for predicting the semantic orientation of words.
