A graphical representation of supersymmetry is presented. It clearly expresses the chiral flow appearing in SUSY quantities, by representing spinors by directed lines (arrows). The chiral suffixes are expressed by the directions (up, down, left, right) of the arrows. The SL(2,C) invariants are represented by wedges. We are free from the messy symbols of spinor suffixes. The method is applied to...

We present a Markov part-of-speech tagger for which the P (w|t) emission probabilities of word w given tag t are replaced by a linear interpolation of tag emission probabilities given a list of representations of w. As word representations, string suffixes of w are cut off at the local maxima of the Normalized Backward Successor Variety. This procedure allows for the derivation of linguisticall...

In this paper we present a lightweight stemmer for Gujarati using a hybrid approach. Instead of using a completely unsupervised approach, we have harnessed linguistic knowledge in the form of a hand-crafted Gujarati suffix list in order to improve the quality of the stems and suffixes learnt during the training phase. We used the EMILLE corpus for training and evaluating the stemmer’s performan...

The suffix tree of string w is a text indexing structure that represents all suffixes ofw. A sparse suffix tree ofw represents only a subset of suffixes of w. An application to sparse suffix trees is composite pattern discovery from biological sequences. In this paper, we introduce a new data structure named sparse directed acyclic word graphs (SDAWGs), which are a sparse text indexing version ...

Discourse Functions in LFG • One school of thought integrates discourse functions such as topic and focus with the grammatical functions at the same level of representation (e.g., Bresnan 2001). • Another school of thought seeks to represent them at an independent level (e.g., King 1997), modeling the interactions in a more complex way. This talk follows the latter position (King 1997) and furt...

New words are constantly entering language. When a new word is formed by the combination of existing morphemes, it is expected to follow languagespecific structural patterns called selectional restrictions. If a new word follows these restrictions, then it can be considered to be morphologically legal, and if it violates these restrictions, then it can be said to be morphologically illegal. For...
