Equity markets and The News – Part I

Traditional economic theory has a well defined position regarding the possible effectiveness of news to determine the future behaviour of equity markets.

One of the basic assumptions, that equity prices essentially perform a random walk around the prevailing trend, would appear to foreclose any likelihood of outperforming the market for any significant period of time. It is claimed that the sheer number and interconnectedness of the variables determining the outcome leads to an intricate interdependent system that can only effectively be modelled using the mathematical concept of a non-linear dynamic system. The essence of a non-linear dynamic system is that minute – practically undetectable – changes in entry conditions may well lead to very significant differences in the outcome. Thus, effectively preventing any meaningful predictions about the future outcome, even if all entry conditions were known.

This leads to a situation of uncertainty which is graphically illustrated by prof. John Allen Paulos (1). He state that all equity market assessments essentially state that “Things will continue roughly as they have been” with the added clause “Until something changes”.

Equity markets and The News – Part II

The relationship between news articles and the behaviour of the stock market has received steady interest by the scientific research community over the last 40 years. With the emergence of effective text analysis technology, and recently with the onset of semantic processing, efforts to capture this relationship have been intensified with (among many others) the following interesting results.

Meditra 3.0 Released

SemLab’s leading triage solution Meditra is about to further raise the standard for medical decision support as the 3.0 version of the application has reached completion. In addition to the fully intuitive graphical interface, and advanced fuzzy reasoning, this version adds an intelligent visual progress monitor cum navigation bar that keeps track of the triage process, summarizes all relevant information and provides instant access to all parts of the program.
Meditra Logo

Furthermore, the 3.0 version adds advanced integration support both for HL7 based communication platforms as to ActiveX based systems, and is available in two versions that each support the unique workflow of either physical or telephone based triage.

We are confident that with this release the Meditra application, already praised for it’s clear and user friendly interface, has again made the difficult job of medical triage a little easier. Together with the unique content of the Netherlands’ Triage System, combining the urgency assessment of ambulance dispatching, General Practioners and Hospital emergency rooms, Meditra is a major contribution to patient safety and readily available to support millions of emergency calls worldwide.

ViewerPro Custom Projects

ViewerPro is a highly flexible and adaptable platform and can be adjusted to accommodate most news impact analysis scenarios. Any specific client desires are analysed by our experts and implemented in a bilateral project in which our customer communicates directly to the ViewerPro development team. This ensures a clear understanding of our customers’ wishes and a fast realization of the required functionality.

Examples of recent projects are the deployment of clients proprietary knowledge repositories for further enhancement of the news analysis and front end user interface integration into an existing trading environment.

Meditra NTS inner workings

We recently received requests about the inner workings of the Meditra Triage application. Especially about its unique feature to allow fuzzy input to be used and its relation to the underlying non-fuzzy triage protocol.  Although the details are subject to non-disclosure, for most purposes the explanation below might suffice.
In the Meditra application the NTS triage criteria are expressed as rules (logical conjunctions) consisting of one or more factor-value combination as the antecedent and an urgency value as the consequent.

The triagist’s input is compared to the full set of rules to determine the resulting urgency. Since the appliation’s user interface allows to express more factor-value combination that are literally present in the ruleset, Mamdani fuzzy inference is used to transform the user input to a firering strength of each involved rule. Within the context of a complaint (ingangsklacht) the resulting fuzzy set of urgencies are defuzzified using defensive robust constraint decision defuzzification.

This strategy allows to evaluate the user input over all complaints and therefore may yield more than one urgency value (one for each complaint). To derive the single resulting urgency value, also a defensive approach is taken as the complaint yielding the highest (most urgent) urgency is assigned to be the “defining complaint” and its urgency the “current urgency”. Once the ruleset of the defining complaint contains no more rules of which the antecedent is a higher urgency class that the current urgency, the current urgency is assigned to be the “final urgency” and the strategy terminates.

ViewerPro for early health risk warning

SemLab is currently proposing a joint research effort, backed by the European Community to deploy their leading event extraction platform ViewerPro in the health risk domain.

SemLab will be leading a consortium of top level technology companies and academia to realise the next level in media monitoring. This project will include speech-to-text functionality, full support for multilinguality, self-learning event extraction and simulation-based event risk assessment.

Semlab researches spatial reasoning in Solim project

The Solim project is now well on its way. Semlab, with partners Picsearch, Tilde and AGMlab are researching the possibilities of image-based content management.

The objective of the Solim project is to improve context-aware information analysis by expansion of state of the art ontology languages and their support for automated reasoning by adding a spatial dimension. This will enable semantic systems to venture beyond a static world and add the concepts of space and change.

Current technological tools for describing semantic knowledge are incapable of adequately supporting automated reasoning on the inherent spatial properties of concepts. Information with a spatial component can be described by using an ontology that treats locations as ordinary concepts. However, in doing so the temporal-spatial consequences of the described events (locations and movement) are lost in the formalisation. This means that knowledge about the spatial aspects (such as orientation, dimension, scale, location and movement of a concept) cannot be efficiently described inside the ontology, even though it comprises valid and persistent knowledge about the domain. Spatial properties can only be dealt with in an ad-hoc manner while these are among the basic properties of physical concepts expressed in many ontologies.

The Solim project extends the ontology web language OWL so that it can support effective storage and reasoning on spatial information, and will demonstrate the power of such an extension with automatic processing of textual and graphical information.
