Description from store This extension takes text and summarizes the text using the TextRank algorithm. The TextRank algorithm is actually based on Google's early PageRank algorithm, which revolutionized how we viewed webpages by assigning importance to links in a set. We use the same basic technology to rank sentences as being more or less important and return the more important sentences.The user has 4 parameters he or she can set if he or she chooses. The number of iterations is the number of times the TextRank algorithm will be run. The idea is that more iterations will produce a better answer, at the cost of efficiency and time. 40 iterations is the default value. There are two other factors which are a bit more confusing: damping factor and delta. The damping rate makes the changing of weights in between iterations less dramatic and delta defines a threshold under which the response is satisfactory. These parameters do not need to be changed by the user but the user can change them if he or she wants. In a paper by Mihalcea and Tarau, describing the algorithm, they state that the value for the damping factor is set to 0.85, which is what we have set it to. The pre-processing on the sentences inputted into the algorithm is limited but sufficient (trim function). The inputted text is pre-processed and made into a graph of frequencies for each word in each sentence over all the words in the document. We then run the PageRank algorithm on the set and get back the sentences and their scores. We sort according to scores and return the number of sentences by scores requested by the user, essentially summarizing the text by importance and relevance.

    There are currently around 650 million Persons with Disabilities (PwD) in the world. According to a study published by StatsSA in 2014, 7.5% of South Africa’s population is understood to live with a disability. This excludes mental health, which from 2015 has also been recognised as a form of disability. Earlier international and national legislation and policies guiding the understanding and approach to working with PwD’s was based on a medical framework of understanding. More recent legislation and policy frameworks are based on a human rights and social understanding. In the medical interpretive framework, PwD’s were understood to be ‘ill/ not medically able’ to fit into society and had to receive special attention and care which was apart from the rest of society. Under the Human Rights Social interpretive framework, which South Africa adopted in 2016, disability as a concept is understood to result from the interaction between persons with impairments and attitudinal and environmental barriers that hinders their full and effective participation in society on an equal basis with others. The need to respect the inherent dignity as well as individual autonomy of PwD’s, to ensure non-discrimination as well as the full and effective participation and inclusion in society of PwD’s is critical.

    Hello, Can I use this app with Word documents? Also, If I can use Word, is there a page limit. I have many documents from 11 to 40 pages and summaries would be very useful to me. Thank you. Paul
