But despite their differences each man deeply valued the other. Darwin persuaded the British government to award Wallace a pension for services to science. Wallace dedicated his book The Malay Archipelago to Darwin, “as a token of personal esteem and friendship but also to express my deep admiration for his genius and his works.” Wallace also called his 1889 collection of evolutionary essays Da...

We present Linkage Query Writer (LinQuer), a system for generating SQL queries for semantic link discovery over relational data. The LinQuer framework consists of (a) LinQL, a language for specification of linkage requirements; (b) a web interface and an API for translating LinQL queries to standard SQL queries; (c) an interface that assists users in writing LinQL queries. We discuss the challe...

In this paper we consider single writer multiple reader concurrency—any number of transactions can atomically access shared data structures, but only one thread can atomically update the data. Limiting ourselves to a single writer allows us to achieve strong properties, some of which are not achievable with multiple writers. In particular, we guarantee strict serializability, no aborts, wait-fr...

In the last several years, we developed new and very effective techniques for automatic writer identification that use probability distribution functions extracted the handwriting images to characterize writer individuality. The demonstration will present a html-based visualization tool that we recently built in order to be able to directly see and assess the results generated by our writer ide...

Writer identification and verification has been studied over the past decade due to the high demand of such implementations in a wide variety of offline handwritten data applications. Among the applications are verification of the identity of a person whom he or she claimed to be and forensic and historic document analysis in identifying the identity of the writer of the documents. This paper p...

Using handwritten characters we address two questions (i) what is the group identification performance of different alphabets (upper and lower case) and (ii) what are the best characters for the verification task (same writer/different writer discrimination) knowing demographic information about the writer such as age,sex or country of birth. The Bhattacharya distance is used to rank different ...
