A natural language parser is a program that works out the grammatical structure of sentences, for instance, which groups of words go together (as "phrases") and which words are the subject or object of a verb. Probabilistic parsers use …

Recursive Deep Models for Semantic Compositionality Over a …

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

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.

GloVe: Global Vectors for Word Representation - Stanford University

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.

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

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.

Stanford NER is a Java implementation of a Named Entity Recognizer. Named Entity Recognition (NER) labels sequences of words in a text which are the names of things, such as person and company names, or gene and protein names.

K-means - Stanford University

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 …

Evaluation of clustering - Stanford University

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 …
