Definitions
- the invention relates to a method for the automatic generation of a summary of a text by a computer.
- a special type of information reduction consists in the merging of texts.
- a method for summarizing texts is known from [1] which uses heuristic features with a discrete range of values.
- the probability that a sentence from the text belongs to the summary on the condition that a heuristic feature has a certain value is estimated from a training set of summaries.
- the object of the invention is to automatically generate a summary from a given text, which summary is intended to represent the essential contents of the text in short form.
- the method according to the invention enables a text to be summarized by determining for each sentence of this text a probability that the sentence belongs to the summary.
- the relevance measure is determined for each word m in the sentence from a lexicon which contains all relevant words with a predefined relevance measure for each of these words.
- the accumulation of all relevance measures gives the probability of the sentence belonging to the summary. All records are then sorted according to their probability.
- a predeterminable reduction measure which indicates what percentage of the original text is shown in the summary, serves for the selection of the number of sentences given by this reduction measure from the sorted representation. If the most important x-percent sentences are selected, they are displayed as a summary of the text in its original order given by this text.
- An advantageous further development of the method according to the invention consists in introducing an frequency of Emzelworth in addition to the relevance measure. This level of detail indicates how often the word in question appears in the entire text to be summarized. Taking into account the relevance measure and this newly introduced
- N is the total number of words in the
- a further development of the method according to the invention consists in using an application-specific lexicon.
- a lexicon specified for sports contributions will rate sports-related words with a higher relevance for a text to be summarized than a lexicon that specializes in summaries of economic contributions. It is therefore advantageously possible to provide specific knowledge about predefinable categories by means of lexica corresponding to the respective categories.
- a text is also advantageous to assign a text to one or more categories. This can be done automatically by using specific, predefinable words in the subject-related lexica as a selection criterion for an assignment to the respective subject area. If several categories (subject areas), i.e. different perspectives or filters, are possible for the summary of a text, different summaries, one for each category, can be created automatically.
- FIG. 1 is a sketch illustrating a system for automatically generating a summary
- Fig. 2 is a block diagram illustrating the steps of the method according to the invention.
- FIG. 1 shows a system with which an automatic generation of a summary of text by a
- a text to be summarized can either be written TXT, e.g. on paper, or in digital form DIGTXT, e.g. as the result of a database query.
- the text TXT is read in by the scanner SC and stored as an image file BD.
- a text recognition software OCR converts the text TXT m present as an image file BD into a machine-readable format, e.g. ASCII format to.
- the digital text DIGTXT is already available in machine-readable format.
- the summary according to the invention is created using the corresponding lexicon (in the KatSel block).
- step 2a the first sentence is selected at the beginning of the method according to the invention and the probability that this sentence belongs to the summary is set to 0.
- step 2b the first word of this sentence is selected. Since the probability that this sentence belongs to the summary is derived from the
- step 2e If the probabilities of the individual words are put together, for each word in the sentence in the loop from step 2c to step 2e, the respective probability is cumulated to the overall probability for the entire sentence. Once all the words in the sentence have been processed, the probability for the individual sentence is normalized by the number of words. The steps described are carried out for all sentences in the text (step 2g, 2h, 2 ⁇ ). If the last sentence in the text has been processed, the sentences are after their
- step 2j Probability sorted (step 2j). According to a predeterminable reduction measure, the n best sentences corresponding to the reduction measure are selected in step 2k and then their original sequence is displayed in step 2m.
