Wolfram Research Inc., makers of Mathematica and A New Kind of Science, have released a limited alpha of their new web service Wolfram Alpha. Wolfram Alpha is described by CEO Stephen Wolfram as a “computational knowledge engine.” Unlike Google, Yahoo! and other traditional web search engines that rely on statistical methods for retrieving online documents, Wolfram Alpha answers factual questions in the way that Wikipedia does, except it relies on analytical methods instead of human-generated documents.

Although the product is still in a limited release some details about its operation and design have been revealed by Wolfram on his blog, and by Nova Spivack who recently interviewed Wolfram about Wolfram Alpha. The product is available on the Web as a single search box reminiscent of Google’s main search page. The search queries can be entered in natural language and the natural language system will parse the query and use models of knowledge (ontologies) and human-curated data to return an answer including graphs and other representations. The ontologies and data are managed by Wolfram employees who must input new ontologies and data by hand or, occasionally, with the assistance of programmatic tools. It is expected that an Application Programming Interface (API) will eventually be available, although it is not known what the API will be used for.

Unlike traditional search engines Wolfram Alpha does not search online documents, and thus does not return answers to “fuzzy” questions, such as opinion or advice. Instead, the scope of answers is limited to the knowledge that has already been modeled and encoded in the ontologies and the associated data. In this way the system can generate knowledge that was previously unknown. It is thought that while Wolfram will concentrate on scientific and technical information the system may eventually be able to answer questions in other domains, such as stock information, geography and history. In theory, any question with a factual answer could be answered by Wolfram Alpha.

Several new developments have occurred surrounding the loss of Philippine ferry MV Princess of the Stars, which capsized and sank on June 21 during a severe storm. The loss near Sibuyan island during Typhoon Fengshen, known locally as Frank, killed more than 800 of those on board.

Ship owner Sulpicio Lines has sued Del Monte Philippines for failing to declare a cargo of the dangerous pesticide endosulfan that was on board. Sulpicio yesterday sued the Board of Marine Inquiry (BMO) for allegedly making comments contributing to negative publicity surrounding the line and asked a court to stop the body continuing its investigation, saying it no longer had any authority. Today, that request was denied.

Another outcome of today’s proceedings is a deadline for Sulpicio to recover the ship. The company has ninety days to ensure the recovery operation is complete.

Yesterday, an eight-page complaint was filed against Del Monte at Manila City‘s regional trial court. It alleges that Del Monte violated the line’s terms by failing to inform Sulpicio that the shipment included edosulfan. The line notes that any toxic cargo should have been declared. Suplicio is seeking PHP5.5 million from the company for alleged negligence.

“Due to Del Monte’s deceit and non-disclosure, plaintiff was led to believe that the subject shipment of Endosulfan was a regular cargo. Had defendant Del Monte disclosed the toxic nature of the cargo, plaintiff would not have loaded the same on board a passenger-cargo vessel, be it MV Princess of the Paradise or MV Princess of the Stars,” said a statement by Suplicio.

The exact total sought as damages is P549,661.11, which accounts for the correct rate for shipping if the toxic cargo had been declared, plus double rates as punitive measures. On top of those damages sought is P3 million to cover specialist recovery required for the chemical, P1 million in moral damges for lost corporate goodwill and damage to Sulpicio’s reputation, P500,000 in moral damages for Sulpicio marketing vice president and shareholder Jordan L. Go, P200,000 in exemplary damages and P300,000 in legal costs.

The discovery that the ship was carrying the endosulfan shipment, which totaled 10 metric tons, led to a ban on fishing in the nearby town of San Fernando and an emergency cessation of search and rescue activities, which were mostly being conducted by divers. The pesticide is banned in many countries and is subject to various regulations in the Philippines. Water samples from the wreck site show that thus far the pesticide has not leaked.

A specialist joint team is set to arrive soon from the European Union and the United Nations Environmental Programme to assist with opearations relating to the pesticide, which is a neurotoxin.

The Philippine Coast Guard yesterday awarded some 42 staff divers and six civilian volunteer divers for their work at the Princess of the Stars. They were particularly praised for being keen to return to work. They are awaiting the results of tests for exposure to endosulfan.

Endosulfan is one of the items set for retrieval in a new deadline set by the government task force overseeing the disaster. Sulpicio must also recover the remaining bodies and the unused fuel on board within 90 days.

Sulpicio had initially offered to have the job done in 164 days, but Transportation Undersecretary Elena Bautista rejected this proposal, saying “Out of humanitarian reasons, I told them not to prolong the agony of the victims’ relatives all the way to Christmas.” Sulpicio was given until Wednesday to name the salvage contractor who would be responsible for recovering the ship, after which they were to submit their retrieval plans to the International Maritime Organisation.

Sulpicio was also given the option of simply towing the ship closer to shore to do the recovery instead of refloating it, which they have opted for. In Bautista’s words: “Based on the Sulpicio report this morning, their plan now is to just tow the vessel to the shore, get the hazardous materials out, get the fuel out, and get the people out and I think that would be more cost-effective and most practical because that can be done, maybe within a month, as compared to refloating, which would probably take three months.”

Sulpicio is currently considering three different potential salvors, which remain unnamed. They have been told that the company needs to have expertise suitable enough to ensure marine life is not harmed and hazardous materials are not spilled. There is a possibility that the planned towing will damage nearby coral. It is already confirmed by the coastguard that oil onboard cannot leak. Most of the 250,000 litres of bunker fuel are in the service tank, which is considered safe. Only the small amount of oil in the base tank may leak but oil spill containment booms are already in place should this occur.

The government has said that, had Sulpicio not made provisions to get the salvage done, then they would have performed the operation themselves. Had this occurred, Sulpicio would have been charged for it, with the bill estimated at P100 million.

One aspect of another legal case was resolved today. Sulpicio had questioned the authority of the BMI to conduct investigations, instead saying only the Maritime Industry Authority (MARINA) had the right to do so, and pointing to a separate inquiry started by MARINA. However, a hearing today found that the BMI and MARINA serve different roles. The BMI’s role is solely to determine the cause of marine accidents. MARINA’s purpose is more concerned with regulations, and is mainly investigating the role of Sulpicio themselves. “We are looking at why we should not cancel the company’s franchise,” explained MARINA Administrator Vicente Suazo Jr.

Both investigations are ongoing.

A 13-hour kidnapping of four people by a bank robber in Setúbal, Portugal, ended at dawn Thursday as members of the special operations group stormed the bank facilities.

The kidnapping started yesterday at about 1400 local time (1300 UTC), when a 57 year old man attempted to rob a Banco Espírito Santo‘s bank at the Rodrigues Manito Avenue, in Setúbal. The alarm was given by a man outside of the bank who noticed the robbery.

The rapid response by the Polícia de Segurança Pública‘s (PSP) district command of Setúbal forced the robber to barricade himself in the bank with two employees and two clients who were in the bank at the time of the robbery. Cornered, the man decided to take the four people hostage, not allowing many contacts on the part of the police negotiators.

According to a PSP source, the kidnapper was armed with a 6.35m pistol and said to the negotiators that he had a explosive device with him. The police immediately sealed off the block and interrupted all telecommunications in the area, only allowing calls to the Portuguese emergency telephone number.

At 0308 local time (0238 UTC) a dozen members of the Police Special Operations Group (GOE) stormed the bank. According to PSP’s officer Manuel Augusto Silva, the kidnapper was armed but was surprised by the members of the GOE team and didn’t react, being immediately arrested.

Some minutes later, the two bank employees, a 20 year old women and a 30 year old man left the bank building. The two clients were then handcuffed and escorted from the building and were not identified.

The last to leave the bank was the kidnapper, who left escorted by the police officers and with his head covered.

As the victims, kidnapper and members of the special forces officers left the bank, a bomb disposal unit entered the bank to inspect the possible bomb of the kidnapper. A suspicious package was later detonated by the technicians following security procedures, but no explosives were found.

Although both the Portuguese authorities and news agencies had said that two of the hostages were female, the hostages were in fact three men and a women. Also, the news of a €100,000 ransom requested by the kidnapper wasn’t confirmed.

“There wasn’t any record of any kind of injuries on the police officers involved, on the four hostages, nor on the detainee” Jerónimo Torrado, officer of the PSP of Setúbal, said.
