IBM advances Watson's ability to understand the language of business - CRN - India

#artificialintelligence

IBM is announcing several new IBM Watson technologies designed to help organizations begin identifying, understanding and analyzing some of the most challenging aspects of the English language with greater clarity, for greater insights. The new technologies represent the first commercialization of key Natural Language Processing (NLP) capabilities to come from IBM Research's Project Debater, the only AI system capable of debating humans on complex topics. For example, a new advanced sentiment analysis feature is defined to identify and analyze idioms and colloquialisms for the first time. Phrases, like'hardly helpful,' or'hot under the collar,' have been challenging for AI systems because they are difficult for algorithms to spot. With advanced sentiment analysis, businesses can begin analyzing such language data with Watson APIs for a more holistic understanding of their operation. Further, IBM is bringing technology from IBM Research for understanding business documents, such as PDF's and contracts, to also add to their AI models.

Sentiment Analysis with Contextual Embeddings and Self-Attention

arXiv.org Artificial Intelligence

In natural language the intended meaning of a word or phrase is often implicit and depends on the context. In this work, we propose a simple yet effective method for sentiment analysis using contextual embeddings and a self-attention mechanism. The experimental results for three languages, including morphologically rich Polish and German, show that our model is comparable to or even outperforms state-of-the-art models. In all cases the superiority of models leveraging contextual embeddings is demonstrated. Finally, this work is intended as a step towards introducing a universal, multilingual sentiment classifier.


Sentiment Analysis Exposed

#artificialintelligence

I made it with Max last night! OMG! Welcome to womanhood!! How was it/he? And right about now, Mary's mom gets a'notification' on her cell phone that her daughter is texting sexual references, then displays Mary's texts with Shelly upon mom's request. Mom spends the rest of the day at work fuming, conjuring dialog with her daughter for later that evening when they'll be home together. Never did, and she'd told Mary not to see him.

Facebook Data Breach: API Security Risks

#artificialintelligence

In the year 2018 Facebook disclosed a massive data breach due to which the company had to face a lawsuit along with allegations of not properly securing its user data. The breach directly affected the authentication tokens of nearly 30 million of its users which led to the filing of several class-action complaints in a San Francisco appeals court. In the wake of the incident, Facebook pledged to strengthen its security. A feature, known as "View As" which was employed by developers to render user pages was exploited by hackers to get access to user tokens. The theft of these tokens is associated with the advancement of a major API security risk, it also indicates how API risks can go unnoticed for such a long time frame.


Annotation of Emotion Carriers in Personal Narratives

arXiv.org Artificial Intelligence

We are interested in the problem of understanding personal narratives (PN) - spoken or written - recollections of facts, events, and thoughts. In PN, emotion carriers are the speech or text segments that best explain the emotional state of the user. Such segments may include entities, verb or noun phrases. Advanced automatic understanding of PNs requires not only the prediction of the user emotional state but also to identify which events (e.g. "the loss of relative" or "the visit of grandpa") or people ( e.g. "the old group of high school mates") carry the emotion manifested during the personal recollection. This work proposes and evaluates an annotation model for identifying emotion carriers in spoken personal narratives. Compared to other text genres such as news and microblogs, spoken PNs are particularly challenging because a narrative is usually unstructured, involving multiple sub-events and characters as well as thoughts and associated emotions perceived by the narrator. In this work, we experiment with annotating emotion carriers from speech transcriptions in the Ulm State-of-Mind in Speech (USoMS) corpus, a dataset of German PNs. We believe this resource could be used for experiments in the automatic extraction of emotion carriers from PN, a task that could provide further advancements in narrative understanding.


Information Extraction from Receipts with Graph Convolutional Networks

#artificialintelligence

As we have seen before, the Information Extraction step consists mainly of classifying words (tagging), the output can be stored as key-value pairs in a computer-friendly file format (e.g.: JSON). The data extracted can then be efficiently archived, indexed and used for analytics. If we compare OCR to young children training themselves to recognize characters and words, then Information Extraction would be like children learning to make sense of the words. An example of IE would be when you stare at your credit card bill trying to find the amount due and the due date. Suppose you want to build an AI application to do it automatically; OCR could be applied to extract the text from the image, converting pixels into bytes or Unicode characters, and the output would be every single character printed in the bill.

Analyzing Customer Support on Social Media - Qualetics Data Machines

#artificialintelligence

The goal of this study is to analyze the queries raised by customers on a particular social media platform by analyzing their interactions with the customer support and provide incisive insights to perform sentiment analysis. We performed exploratory data analysis to extract insights from the data. With Deep Learning tools like NLTK, sentiment analysis was performed to understand the positive, negative, and neutral sentiments of the customers of a brand. Machine Learning was used to identify the frequency of similar text appearances. Deep learning algorithms were used to understand the customer queries and the average time taken by the respective company's social customer support team in addressing the queries.
