GloVe: Global Vectors for Word Representation

(53 years ago) GloVe is an unsupervised learning algorithm for obtaining vector representations for words. Training is performed on aggregated global word-word co-occurrence statistics from a corpus, and the resulting representations showcase interesting linear substructures of the word vector space.

A Part-Of-Speech Tagger (POS Tagger) is a piece of software that reads text in some language and assigns parts of speech to each word (and other token), such as noun, verb, adjective, etc., although generally computational applications use more fine-grained POS tags like 'noun-plural'.

Recursive Deep Models for Semantic Compositionality Over a …

(53 years ago) This website provides a live demo for predicting the sentiment of movie reviews. Most sentiment prediction systems work just by looking at words in isolation, giving positive points for positive words and negative points for negative words and then summing up these points. That way, the order of words is ignored and important information is lost. In constrast, our new deep learning …

The Stanford Natural Language Processing Group

(53 years ago) The Charniak-Johnson parser includes a model for parsing English. The Bikel parser requires users to train their own model, which can be done using the included train-from-observed utility and the model data linked above. The RelEx package is rule-based and provides a Stanford Dependency compatibility mode.

Single-Link, Complete-Link & Average-Link Clustering

(53 years ago) There is now an updated and expanded version of this page in form of a book chapter. Single-Link, Complete-Link & Average-Link Clustering. Hierarchical clustering treats each data point as a singleton cluster, and then successively merges clusters until all points have been merged into a single remaining cluster.

An example information retrieval problem - Stanford University

(53 years ago) Let us now consider a more realistic scenario, simultaneously using the opportunity to introduce some terminology and notation. Suppose we have documents. By documents we mean whatever units we have decided to build a retrieval system over. They might be individual memos or chapters of a book (see Section 2.1.2 (page ) for further discussion).We will refer to the group …

Processing Boolean queries - Stanford University

(53 years ago) For arbitrary Boolean queries, we have to evaluate and temporarily store the answers for intermediate expressions in a complex expression. However, in many circumstances, either because of the nature of the query language, or just because this is the most common type of query that users submit, a query is purely conjunctive.

Evaluation of clustering - Stanford University

(53 years ago) where, again, the second equation is based on maximum likelihood estimates of the probabilities. in Equation 184 measures the amount of information by which our knowledge about the classes increases when we are told what the clusters are. The minimum of is 0 if the clustering is random with respect to class membership. In that case, knowing that a document is in a particular …

K-means - Stanford University

(53 years ago) The first step of -means is to select as initial cluster centers randomly selected documents, the seeds.The algorithm then moves the cluster centers around in space in order to minimize RSS. As shown in Figure 16.5, this is done iteratively by repeating two steps until a stopping criterion is met: reassigning documents to the cluster with the closest centroid; and recomputing each …

Edit distance - Stanford University

(53 years ago) The spelling correction problem however demands more than computing edit distance: given a set of strings (corresponding to terms in the vocabulary) and a query string , we seek the string(s) in of least edit distance from .We may view this as a decoding problem, in which the codewords (the strings in ) are prescribed in advance.The obvious way of doing this is to compute the edit …

Mutual information - Stanford University

(53 years ago) End worked example. To select terms for a given class, we use the feature selection algorithm in Figure 13.6: We compute the utility measure as and select the terms with the largest values.. Mutual information measures how much information - in the information-theoretic sense - a term contains about the class.
