 However, for linguists working in the field of corpora, there presents a number of challenges.This includes the limited instances that are presented by the search engines (1,000 or 5,000 maximum); insufficient context for each instance (Google provides a fragment of around ten words); results selected according to criteria that are distorted (from a linguistic point of view) as search term in titles and headings often occupy the top results slots; inability to allow searches to be specified according to linguistic criteria, such as the citation form for a word, or word class; unreliability of statistics, with results varying according to search engine load and many other factors.At present, in view of the conflicts of priorities among the different stakeholders, the best solution is for linguists to attempt to correct these problems by themselves.
