Advanced Training Set Construction for Retrieval in Historic Documents
Retrieval in historic documents with non-standard spelling requires a mapping from search terms onto the historic terms in the document. For describing this mapping, we have developed a rule-based approach. The bottleneck of this method has been the training set construction for the algorithm where an expert has to assign manually current word forms to historic spelling variants. As a better solution, we apply a spell checker on a corpus of historic texts, which gives us a list of candidate terms and associated suggestions. The new method generates possible rules for the suggestions and accepts the most frequent rules. Experimental results with German and English texts from different centuries demonstrate the feasibility of our approach. Thus a training set can be constructed with much less initial effort. Key words: Spelling variation, training set construction, historic documents
