La littérature française comprend l'ensemble des oeuvres écrites par des auteurs de nationalité française ou de langue française, elle peut également se référer à la littérature écrite par des citoyensfrançais qui écrivent dans des langues de France telles que le basque, le breton, etc. Le mot littérature dérive du terme latin litterae, qui désigne l'ensemble des savoir-faire pour écrire et lire bien. Le concept est associé à l'art de la grammaire, de la rhétorique et de la poétique.D'après le Trésor de la Langue Française informatisé (TLFi), la littérature est l'art qui se sert d'une langue comme moyen d'expression. Le vocable est également utilisé pour désigner l'ensemble des productions littéraires d'une nation, d'une époque ou d'un genre (comme la littérature perse, par exemple) et l'ensemble des oeuvres portant sur un art ou une science (littérature sportive, littérature juridique, etc.).

In the problems of fragmentation, density, duplication and selection of passages, the summarization of several documents ranges from the summarization of single documents to the creation of efficient summaries. Our approach addresses these issues by using Agglomerative cluster sentence, GloVe, TextRank, Cosine Similarity. In addition, this research also use NLTK as library filter word such as stopwords, numeric, punctuation, multiple_whitespaces, short_words in order Vectorizing the sentence when using GloVe. The result of this paper was evaluated using ROUGE; 41% for unigram, 17% for bigram, 57% for trigram.

Several experiments by using different methodologies have been performed to answer the stock market forecasting issues. A traditional linear model, like autoregressive integrated moving average (ARIMA) has been used, but the result is not satisfactory because it is not suitable for model financial series. Yet experts are likely observed another approach by using artificial neural networks. Artificial neural network (ANN) are found to be more effective in realizing the input-output mapping and could estimate any continuous function which given an arbitrarily desired accuracy. In details, in this paper will use maximal overlap discrete wavelet transform (MODWT) and graph theory to distinguish and determine between low and high frequencies, which in this case acted as fundamental and technical prediction of stock market tradin...
