With the help of this system, one would be able to search any keyword through thousands of documents in a fully automatic manner. Firstly, given a document collection, it is preprocessed by a binarization method, and small noises are cleaned by removing connected components smaller than a predefined threshold. Then, the pages are segmented into lines by a run-length smoothing algorithm. Words are then manually extracted and represented by patch-based and column-based features. The similarity between words is calculated by the Euclidean distance of feature vectors and words are ready to be matched based on a threshold of their similarity. An indexing and retrieval schema is provided for all words in the collection so that a user can search keywords like a search engine and retrieve all documents related to that keyword. Our experiments on an Ottoman collection show promising results for both intra- and cross-document word retrieval schemes.

The Ottoman Empire, which lasted for more than 6 centuries (1299-1922) and spread over 3 continents, was one of the most powerful states of its time. More than 150 million historical documents produced constitute a large heritage and attract the interest of scholars from many disciplines such as history, literary studies, sociology and from many different countries.
