    • Could context-dependent relationships be recovered from word embeddings? To address this issue, they introduce a powerful, domain-general solution: "semantic projection" of word-vectors onto lines that represent various object features, like size (the line extending from the word "small" to "big"), intelligence (from "dumb" to "smart"), or danger (from "safe" to "dangerous").

Extractive Text Summarization

  1. H. P. Luhn. The automatic creation of literature abstracts. IBM Journal of Research and Development, 1958. Luhn's method is as follows:
    1. Ignore Stopwords: Common words (known as stopwords) are ignored.
    2. Determine Top Words: The most often occuring words in the document are counted up.
    3. Select Top Words: A small number of the top words are selected to be used for scoring.
    4. Select Top Sentences: Sentences are scored according to how many of the top words they contain. The top four sentences are selected for the summary.
  2. H. P. Edmundson. New Methods in Automatic Extracting. Journal of the Association for Computing Machinery, 1969.
  3. David M. Blei, Andrew Y. Ng and Michael I. Jordan. Latent Dirichlet Allocation. Journal of Machine Learning Research, 2003. The source code in Python is sklearn.decomposition.LatentDirichletAllocation. Reimplement Luhn's algorithm, but with topics instead of words and applied to several documents instead of one.
    1. Train LDA on all products of a certain type (e.g. all the books)
    2. Treat all the reviews of a particular product as one document, and infer their topic distribution
    3. Infer the topic distribution for each sentence
    4. For each topic that dominates the reviews of a product, pick some sentences that are themselves dominated by that topic.
  4. David M. Blei. Probabilistic Topic Models. Communications of the ACM, 2012.
  5. Rada Mihalcea and Paul Tarau. TextRank: Bringing Order into Texts. ACL, 2004. The source code in Python is pytextrank. pytextrank works in four stages, each feeding its output to the next:
    • Part-of-Speech Tagging and lemmatization are performed for every sentence in the document.
    • Key phrases are extracted along with their counts, and are normalized.
    • Calculates a score for each sentence by approximating jaccard distance between the sentence and key phrases.
    • Summarizes the document based on most significant sentences and key phrases.
  6. Federico Barrios, Federico López, Luis Argerich and Rosa Wachenchauzer. Variations of the Similarity Function of TextRank for Automated Summarization. arXiv:1602.03606, 2016. The source code in Python is gensim.summarization. Gensim's summarization only works for English for now, because the text is pre-processed so that stop words are removed and the words are stemmed, and these processes are language-dependent. TextRank works as follows:
    • Pre-process the text: remove stop words and stem the remaining words.
    • Create a graph where vertices are sentences.
    • Connect every sentence to every other sentence by an edge. The weight of the edge is how similar the two sentences are.
    • Run the PageRank algorithm on the graph.
    • Pick the vertices(sentences) with the highest PageRank score.
  7. TextTeaser uses basic summarization features and build from it. Those features are:
    • Title feature is used to score the sentence with the regards to the title. It is calculated as the count of words which are common to title of the document and sentence.
    • Sentence length is scored depends on how many words are in the sentence. TextTeaser defined a constant “ideal” (with value 20), which represents the ideal length of the summary, in terms of number of words. Sentence length is calculated as a normalized distance from this value.
    • Sentence position is where the sentence is located. I learned that introduction and conclusion will have higher score for this feature.
    • Keyword frequency is just the frequency of the words used in the whole text in the bag-of-words model (after removing stop words).
  8. Güneş Erkan and Dragomir R. Radev. LexRank: Graph-based Lexical Centrality as Salience in Text Summarization. 2004.
    • LexRank uses IDF-modified Cosine as the similarity measure between two sentences. This similarity is used as weight of the graph edge between two sentences. LexRank also incorporates an intelligent post-processing step which makes sure that top sentences chosen for the summary are not too similar to each other.

Abstractive Text Summarization

  1. Alexander M. Rush, Sumit Chopra, Jason Weston. A Neural Attention Model for Abstractive Sentence Summarization. EMNLP, 2015. The source code in LUA Torch7 is NAMAS.
    • They use sequence-to-sequence encoder-decoder LSTM with attention.
    • They use the first sentence of a document. The source document is quite small (about 1 paragraph or ~500 words in the training dataset of Gigaword) and the produced output is also very short (about 75 characters). It remains an open challenge to scale up these limits - to produce longer summaries over multi-paragraph text input (even good LSTM models with attention models fall victim to vanishing gradients when the input sequences become longer than a few hundred items).
    • The evaluation method used for automatic summarization has traditionally been the ROUGE metric - which has been shown to correlate well with human judgment of summary quality, but also has a known tendency to encourage "extractive" summarization - so that using ROUGE as a target metric to optimize will lead a summarizer towards a copy-paste behavior of the input instead of the hoped-for reformulation type of summaries.
  2. Peter Liu and Xin Pan. Sequence-to-Sequence with Attention Model for Text Summarization. 2016. The source code in Python is textsum.
    • They use sequence-to-sequence encoder-decoder LSTM with attention and bidirectional neural net.
    • They use the first 2 sentences of a document with a limit at 120 words.
    • The scores achieved by Google’s textsum are 42.57 ROUGE-1 and 23.13 ROUGE-2.
  3. Ramesh Nallapati, Bowen Zhou, Cicero Nogueira dos santos, Caglar Gulcehre, Bing Xiang. Abstractive Text Summarization Using Sequence-to-Sequence RNNs and Beyond. arXiv:1602.06023, 2016.
    • They use GRU with attention and bidirectional neural net.
    • They use the first 2 sentences of a documnet with a limit at 120 words.
    • They use the Large vocabulary trick (LVT) of Jean et al. 2014, which means when you decode, use only the words that appear in the source - this reduces perplexity. But then you lose the capability to do "abstractive" summary. So they do "vocabulary expansion" by adding a layer of "word2vec nearest neighbors" to the words in the input.
    • Feature rich encoding - they add TFIDF and Named Entity types to the word embeddings (concatenated) to the encodings of the words - this adds to the encoding dimensions that reflect "importance" of the words.
    • The most interesting of all is what they call the "Switching Generator/Pointer" layer. In the decoder, they add a layer that decides to either generate a new word based on the context / previously generated word (usual decoder) or copy a word from the input (that is - add a pointer to the input). They learn when to do Generate vs. Pointer and when it is a Pointer which word of the input to Point to.

    • They addressed an important problem in sequence-to-sequence (Seq2Seq) learning referred to as copying, in which certain segments in the input sequence are selectively replicated in the output sequence. In this paper, they incorporated copying into neural network-based Seq2Seq learning and propose a new model called CopyNet with encoder-decoder structure. CopyNet can nicely integrate the regular way of word generation in the decoder with the new copying mechanism which can choose sub-sequences in the input sequence and put them at proper places in the output sequence.

    • They compared modern extractive methods like LexRank, LSA, Luhn and Gensim’s existing TextRank summarization module on the Opinosis dataset of 51 (article, summary) pairs. They also had a try with an abstractive technique using Tensorflow’s algorithm textsum, but didn’t obtain good results due to its extremely high hardware demands (7000 GPU hours).

  2. Baotian Hu, Qingcai Chen and Fangze Zhu. LCSTS: A Large Scale Chinese Short Text Summarization Dataset. 2015.
    • They constructed a large-scale Chinese short text summarization dataset constructed from the Chinese microblogging website Sina Weibo, which is released to the public. Then they performed GRU-based encoder-decoder method on it to generate summary. They took the whole short text as one sequence, this may not be very reasonable, because most of short texts contain several sentences.
    • LCSTS contains 2,400,591 (short text, summary) pairs as the training set and 1,106 pairs as the test set.
    • All the models are trained on the GPUs tesla M2090 for about one week.
    • The results show that the RNN with context outperforms RNN without context on both character and word based input.
    • Moreover, the performances of the character-based input outperform the word-based input.
