“…Attempts to use genetic programming for natural language processing are uncommon, although early applications to language processing tasks can be found as early as our work using GP to aid in recovery from parser failure in speech-to-speech machine translation in the late 90s [20]. Lately, there has been a large body of work for applying genetic programming to query generation for information retrieval [6], in uses related to ours, such as query expansion [1] and tree-based genetic programming for query generation [22].…”

“…For each word that actually does occur in that document, the corresponding attribute is set to a value of 1; all other attributes are set to a value of 0. This is also known as a unigram model 1 . Interactions between simple features are useful to capture in language processing tasks.…”

“…Instead, it has been suggested in previous work to use the document scores as the fitness [14]. While this may not be intuitive, it turns out that variations of these scores after expansion are correlated with relevance [1]. One intuitive explanation Table 3 Global precision results for the whole set of tested queries.…”
