FAQs

What is Summazer?
Summazer is the free app to summarize a text or a web page and extract its juice, that is the sentences with the highest information content, to generate an automatic online summary of the processed text. The app incorporate a powerful spell checker that allows you to identify any incorrectly written words on the fly and, if necessary, correct them with a click on the suggested words.
In addition to highlighting the most important phrases, Summazer allows you to analyze, with a graph, the trend of semantic relevance within the text, in order to provide an immediate picture of the sections of the text to which you want to give greater evidence (typically a good text - especially if it is intended for the Web , should carry the salient parts at the beginning and at the end in order to immediately provide the reader with the meaning of the message you want to provide). Finally, Summazer reports an innovative indicator of the "summarizability" of the processed text (SoT).
If the summarizability (SoT) is low it may depend on the presence of spelling errors, excessive use of obsolete or foreign words, or the processed text is full of sentences that are not very related to each other from a semantic point of view (as happens, for example, if you summarize an entire web page, instead of selecting and pasting only the text that actually conveys the meaning of the article).
What is the optimal percentage for summarising?
The percentage depends on the length of the text to be summarised: for long texts it is advisable to set 30%, for very long texts to set 10%, for short texts 50% of the length of the text entered may be sufficient.
Why should the spell-checker be enabled?
In order to optimise the quality of the summary to be processed, it is essential that the words in the text to be analysed are spelt correctly and recognised by the vocabulary of the selected language. By enabling the spell-checker, you will be able to identify any terms that are not spelled correctly or not recognised in the vocabulary of the selected language. If you believe that an unrecognised term should be added to Nelsenso.Net's vocabularies, you can add it. If this addition is approved, it will be available the next day.
What does Summazer return?
Summazer returns the following outputs:
  • It identifies the typology of the text elaborated, currently the recognized typologies include: narrative passages, argumentative texts and informative texts .
  • Extracts the principal named entities (proper names, locations, etc ...) in the form of hashtags for which it is then possible to search for images using the "Unsplash" search engine ( Unsplash: Beautiful Free Images & Pictures) to enrich your post, article or essay.
  • Highlight sentences with the highest information content in the elaborated text.
  • It also provides a series of graphs to highlight the "behind the scenes" of the application, that is: the analysis of the trend of the semantic relevance within the processed text and the statistical distribution (Gaussian) of the semantic relevance . Long and well-written texts will be characterized by narrow bell curves shifted far to the right with respect to the ordinate axis (i.e. texts with a high expected value of semantic relevance and few frequency values ​​cluster around the average value). On the other hand, texts that cannot be summarized (because they have several paragraphs that are not semantically related to each other) are characterized by large bells centered with respect to the ordinate axis, or with a very low expected value.
What is Summazer's summarisability indicator (SoT)?
Summazer reports an innovative indicator of how summarisable the processed text is (SoT: Summarisability of the Text).
If the summarisability index (SoT) is low, it may depend on spelling errors, on an excessive use of obsolete or foreign words, or on a text full of sentences that are poorly related to each other from a semantic point of view; this happens, for example, if you summarise an entire web page instead of selecting and pasting only the text that actually conveys the meaning of the article.
Why use an automatic text summarizer?
Whether you have a page from a school textbook, a research paper, a blog post, a newspaper article or any other document, Summazer gives you the essential information you are looking for.
What are the advantages of using Summazer?
  • Summazer generates instant summaries: you do not need to read the whole document to get its main ideas.
  • It increases productivity: looking for a few important pieces of information in a web article takes time and effort.
  • It makes studying easier: Summazer helps students immediately find the gist of their long essays and other school or academic material, so they can summarise handouts and notes without any obstacle.
How do I get a summary from a photo of a text?
To summarise a text starting from a photo, use the Summarize a photo page: take a photo of a book page or of your notes (or upload it from your gallery) and Summazer reads the text from the image directly on your device and summarises it. However, do not forget to correct any reading errors with the online spell checker built into Summazer.
Exhaustiveness: what does it mean?

The index of Exhaustiveness refers to the level of logical-grammatical completeness of the sentences extracted from the apps to generate the summary of the elaborated text. A high Exhaustiveness index is preferable if the processed text comes from a web page that contains different types of texts that are often poorly related to the main body of the text. A medium-low Exhaustiveness index is preferable for narrative/argumentative texts (text plain).
What is the automatic summary of a text?
The automatic summary of a text is a process that allows you to automatically transform a source text into a shorter text that contains the most semantically relevant information.
