The Future

• One method for concept searching and determining semantics between phrases is Latent Semantic Indexing/Latent Semantic Analysis (LSI/LSA).
• Kasisto delivers Kasisto Kai, a chatbot which customers can communicate with on Facebook Messenger, SMS and Slack.
• We support CTOs, CIOs and other technology leaders in managing business critical issues both for today and in the future.
• Concepts like irony and metaphors that come second nature to us are lost on computers.
• Quantum information retrieval has the remarkable virtue of combining both geometry and probability in a common principled framework.

Within the field of Natural Language Processing (NLP) there are a number of techniques that can be deployed for the purpose of information retrieval and understanding the relationships between documents. The growth in unstructured data requires better methods for legal teams to cut through and understand these relationships as efficiently as possible. The simplest way of finding similar documents is by using vector representation of text and cosine similarity. One method for concept searching and determining semantics between phrases is Latent Semantic Indexing/Latent Semantic Analysis (LSI/LSA).

The approaches followed by both QLSA and LSA are very similar, the main difference is the document representation used. LTA methods based on probabilistic modeling, such as PLSA and LDA, have shown better performance than geometry-based methods. However, with methods such as QLSA it is possible to bring the geometrical and the probabilistic approaches together. In my view the difference between LSI and LSA is slight – while LSI builds a term by document matrix, LSA has often relied on term by article matrices (hoping to better capture the semantics of words and phrases).

Synonymy is often the cause of mismatches in the vocabulary used by the authors of documents and the users of information retrieval systems. As a result, Boolean or keyword queries often return irrelevant results and miss information that is relevant.

Concepts like irony and metaphors that come second nature to us are lost on computers. With NLP financial institutions can monitor the direction of a stock and keep tabs on public speculation. When the value of assets is so dependent on public opinion it can be very difficult to stay on the right side of the market. By analysing natural language, online banks and other institutions can keep tabs on public perception. Sentiment analysis has an innate appeal to financial institutions because it provides a means to anticipate how the market is moving. AI is used by many financial institutions such as JP Morgan in an attempt to improve trading, fund management and risk control strategies.

• Of all the applications of NLP there is one that outshines all others; sentiment analysis.
• The simplest way of finding similar documents is by using vector representation of text and cosine similarity.
• One of the most well-known chatbots platforms in the financial industry has been designed by Kasisto.
• A critical limitation of this approach was that it failed to address the unconscious human ability to source vast amounts of data collected over the course of a human’s life.
• Computers have a tendency to ignore the subtle nuances in favor of black and white interpretations.
• Chatbots function well within the finance industry because they allow organisations to automate routine customer service activity.

How modern enterprises are Using NLP sentiment analysis

It’s more challenging than it sounds; aspects are often domain-sensitive and share close semantic similarity. For instance, an opinion that might be considered positive in the context of a movie review (e.g. “delicate”) may be negative in another (a cell phone review). Quantum information retrieval has the remarkable virtue of combining both geometry and probability in a common principled framework. The quantum-motivated representation is an alternative for geometrical latent topic modeling worthy of further exploration.

They are near synonyms where the difference depends on your application (IR or lexical semantics) or perhaps your orientation (retrieval tool versus cognitive model). LSI/LSA is an application of Singular Value Decomposition Technique (SVD) on the word-document matrix used in Information Retrieval. LSA is a NLP method that analyzes relationships between a set a documents and the terms contained within. However, it has also found use in software engineering (to understand source code), publishing (text summarization), search engine optimization, and other applications. Customers can communicate with chatbots to receive real-time updates, answers to questions and messages if fraudulent activity is detected.

What makes sentiment analysis viable is that it can translate the unstructured opinions of consumers into transparent insights on products or services. Decision makers can then use this data to develop a more in depth understanding of their target audience. Nowhere is this more apparent than the financial industry where NLP is used for general sentiment analysis and for chatbots. One application it didn’t target was sentiment analysis, which involves detecting subjective information from text, but that’s changing courtesy a newly announced update. The most prominent researcher in the team was Susan Dumais, who currently works a distinguished scientist at Microsoft Research.

When you load up a voice recognition application like Siri, NLP is being used to interpret everything you say into the microphone. As these programs become more sophisticated they will become better able to tackle the nuance of human language. A number of experiments have demonstrated that there are several correlations between the way LSI and humans process and categorize text. This is because traditionally, imbuing machines with human-like knowledge relied primarily on the coding of symbolic facts into computer data structures and algorithms. A critical limitation of this approach was that it failed to address the unconscious human ability to source vast amounts of data collected over the course of a human’s life. This also fails to address important questions about how humans acquire and represent this data in the first place.

Text summarisation, deep learning and semantic search offer companies from all sectors lots of opportunities in the near future. Chatbots function well within the finance industry because they allow organisations to automate routine customer service activity. Rather than paying a representative to answer questions live, a bank can invest in a chatbot to manage lower priority support tasks.
